We came to Istanbul for the 2012 New years eve and this hotel seemed to be a nice accomodation close to both Taxim square and old town and it had good reviews on booking.com so we made a reservation.
Well first off, it turned out that the hotel isnt so easy to find since it has no signs at all. But even after we had it found we couldn't come in since the door was locked! We called the number given on reservation but nobody answered. It was too late to leave and try to find some other place to stay (after 9pm) especially because there weren't a lot of places in the neighbouring area. There's a small coffee shop nearby so we asked the owner to call someone and let us in. In some 20-30 minutes time a guy finally showed up and we got a room...
The room was comparatively big and VERY dirty! There's no reception desk there and during our stay (3 nights) we havent seen either anyone from the hotel's stuff or room cleaning. We basically has got no service at all! The only person we found there was a woman running a cafe downstairs who didnt speak english :) At least she managed to explain (in German) where we could find clean towels.
I am not sure if it was the way the owners run their hotel, or we just had some bad luck, but it was the worst place we've ever stayed in! We had a horrible experience and btw even though we left earlier the hotel charged us the full price (they charged the credit card directly since nobody ever showed up).
